Kurt Böhnisch, Nora's boss, is retired and takes his own life during his farewell party. The LKA Kiel is in shock. Shortly after Böhnisch's suicide, a woman's body is found in Lübeck. Nora discovers similarities with an unsolved murder of a woman in Rostock. Böhnisch had searched in vain for his daughter Jasmin, who lived in Rostock and disappeared without a trace two years ago. Was she also a victim of a crime? Together with Simon Brandt from the Lübeck Criminal Police Office, Nora Weiss investigates the matter, but encounters a wall of silence among her colleagues in Rostock and some contradictions in the investigations to date. As she gets closer and closer to the truth, the perpetrator sets his sights on Nora.
